350-701 Practice Question: Secure Network Access, Visibility and Enforcement
A Cisco TrustSec deployment is being implemented to enforce micro-segmentation. The security team needs to ensure that Security Group Tags (SGTs) are propagated across the network. Which THREE methods can be used to distribute SGT information in a TrustSec environment? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SGT over SXP (SGT Exchange Protocol)
The correct methods are SGT over SXP (SGT Exchange Protocol), SGT over VXLAN, and SGT inline tagging in the Ethernet header. SGT over MPLS is not a standard TrustSec propagation method. SGT over CDP is not supported; CDP is used for device discovery, not SGT propagation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SGT over SXP (SGT Exchange Protocol)
Why this is correct
SXP is a standard protocol to propagate SGTs between network devices without inline tagging.
- ✗
SGT over Cisco Discovery Protocol (CDP)
Why it's wrong here
CDP is not designed for SGT propagation.
- ✓
SGT over VXLAN
Why this is correct
SGTs can be carried in VXLAN headers for overlay networks.
- ✓
SGT inline tagging (in the Ethernet header)
Why this is correct
Inline tagging inserts SGT into the Ethernet frame header between source MAC and EtherType.
- ✗
SGT over MPLS
Why it's wrong here
MPLS does not natively support SGT propagation in TrustSec.
